My invention has relation to certain new and useful improvements on machines for compressing into compact bundles loose sticks of woodsuch, for instance, as sawed kindling-wood-and holding the compressed sticks together while they are tied or bound, and

then releasing the tied bundles and automatioally ejecting them, as will be more fully hereinafter set forth.

The object of this invention is to improve and simplify the construction, generally, of the compressing and ejecting devices, whereby a positively-operating and practical machine that will perform its work rapidly and thoroughly is produced, as will presently appear.

As the principle and advantages of this machine will be better understood from a detail description of its construction and operation, I will now proceed to describe it, referring to the accompanying drawings by letters.

A designates a suitable base or frame, having erected upon its forward end a standard or support, B, which supports the compressing and forming devices.

Journaled in suitable bearings erected'on the base A is a transverse shaft, 0, provided with a driving-pulley, D, and a cam wheel or disk, E, which is capable of a limited longitudinal movement on the shaft, (being attached thereto by a feather, a,) but rotates with it. This disk is adjusted on the shaft by means of a pivoted angle lever, F, operated by a pivoted hand-lever, G, the bifurcated end of the angle-lever being provided with suitable pins, which engage an annular groove in a sleeve formed integral with the disk. The lever is limited in its movements by a guard, H, secured to the base.

It is evident that I may employ other arrangements of shifting-levers without departing from my invention in the least.

Formed on the face of the disk E is a spiral cam, I, which starts at a point at or near the edge of the disk and terminates near its cenv ter, as clearly shown in Figs. 1 and 4. This spiral cam is adapted to engage an anti-friction roller or pin, J, on a lever, K, pivoted at b to the base and provided with an adjustable weight, L. This lever is guided in its vertical movements .by means of the guides M, formed integral or bolted to the base, and is limited in its downward movement by the stop N, adapted to abut against a projection, c, on the base. When the spiral cam is thrown by means of the levers into engagement with the pin J on the lever, the same is gradually elevated as the cam-disk is rotated, and as it is moving upward its rear end conlooks the bar in an elevated position. This locking-bar slides in a suitable bearing or support, P, bolted to the base, and is provided at its rear end with a lateral arm, Q, which has j ournaled in its face an anti-friction roller adapted to contact with the back of the rotating cam-disk when the same is disengaged from the lever K, as shown in Fig. 6. The arm Q has attached to it a rod, R, which passes through and is supported at its free end by a stationary arm on the base, a spring being interposed between this stationary arm and the movable arm Q, the object of this spring being to keep the lockingbar normally pressed forward.

It is evident that when the cam-disk is disengaged from the lever the disk will, through the medium of the arm Q and anti-friction roller, withdraw the locking-bar and permit the lever to fall, its weight L serving to carry it down quickly and positively. It will also be observed that when the cam-disk is thrown forward into engagement with the lever K the locking-bar will automatically project itself ready to engage the lever when it is brought up again by the cam.

Pivotally connected to the forward end of the lever K by means of an adjustable clip, S, and a pivotal bolt, (1, is the lower end of a connecting-rod, T, the lower end of the connecting-rod being preferably bifurcated to embrace the adjustable clip and lever. By adjusting the clip S. along the lever by means of a screw, e, as shown clearly in Fig. 13, the throw of the connecting-rod may be regulated. The upper end of this connecting-rod is tapped into a clip or clevis, f, which is pivotally connected to the rear end of an arm, U, working in a vertical slot in the standard and pivoted between ears g, cast on the face of the same. The forward end of this arm or lever U is provided with cars It, and to these cars are pivoted the inner ends of two toggle-levers, V V. The lower end of the lower one of these levers is pivoted to a sliding cross-head or block, W, provided with a projection or tongue, 2', which fits in a vertical slot in the standard, this tongue being held in its slot by means of a plate, j, bolted to it.

The upper end of the upper toggle is pivoted to the lower compressor or former, X, provided with tongues k,which also fit into vertical guiding-slots in the standard, and are held therein by means of the plates Z Z, bolted to the tongues and resting against the rear side of the standard. This former or compressor is approximately U shaped, and is provided with grooves in its vertical edges, and projecting into these grooves from the body of the former are two beveled or inclined lugs, m on, for apurpose hereinafter set forth.

Bolted adjustably by means of bolts n and set-screws p in grooves in the cross-head WV are the clips Y Y, and pivotally attached to these clips are the links Z Z. The upper ends of these links are pivotally clamped between the respective ends of two spring-yokes, A

A, these yokes embracing the former X and resting in the guiding-grooves in its vertical edges, the beveled lugs m being of such a thickness as to pass in between the yokes, as shown in Figs. 1 and 2. v

The parts of the compressing and forming devices not heretofore described operate as follows: After the tying-cord has been placed between the yokes and in a groove formed in the upper face of the former, the bunch or bundle of sticks to be compressed and tied is first placed in the former or follower, after which the continuously-rotating cam-disk is thrown into engagement with the pin on the lever K. As this disk revolves in the direction indicated by the arrow on Fig. 1, the rear end of the lever K is elevated and its forward end depressed, carrying with it the connecting-rod T, which in turn pulls down on the arm U. As the rear end of the arm U is depressed, the toggles V V will be forced, respectively, upwardly and downwardly, thus moving the lower former, X, and cross-head \V slowly away from each other-that is, the former upwardly and the cross-head downwardly. As the cross-head moves downwardly, it draws the elastic yokes down with it, clamping and compressing into a compact bundle the sticks placed between the movable yokes and U-shaped former. After the bundle is tied the cam-disk is disengaged from the lever K and the lever permitted to drop, in the manner hereinbefore set forth. As the rear end of the lever falls, the forward end of it is elevated and the toggles thereby carried back to their former position, and as the toggles are opened the bundle will be released, the yokes moving upward and the former or follower X being drawn down. As the yokes A and links Z move upward, the upper inner ends of the latter contact with the beveled lugs m m on the follower, and are thereby forced outward, carrying with them the ends of the yokes, the elastic or spring portion of the yokes permitting this to be done. The object in thus laterally spreading the yokes A A is to release the tied bundle, in order that it may be ejected quickly and easily. By this arrangement of the spiral cam and toggle-levers, it will be perceived, a powerful pressure may be exerted upon the bundle, thus bringing-the sticks of the bundle into very close contact.

The bundle-ejector is constructed and operated as follows:

The ejector-plate B has attached to it two rods or pins, (1 q, which work in guiding sleeves or tubes 1" 0*, formed integral with a ring, 0, bolted to the rear side of the standard B. This ejector-plate is connected to the vertical arm of an angle-lever, D, by means of a pivotal link, E, which passes through the center of a ring, 0, and is pivotally attached to the center of the ejector-plate. The anglelever is pivoted in cars on the rear side of the standard, and it has its horizontal arm provided with a weight, .9. Pivotally attached to the weighted arm of the angle-lever and de-- pressed, tied, and released, and the weighted end of the lever K falls in the manner hereinbefore set forth, the forward end of this lever comes in contact with the lower end of the rod F and elevates the same. As this rod moves upward, the ej ecting-plate, through the medium of the angle-lever and pivotal link, is thrown forward, so as to eject the bundle from the compressing devices. In order to permit the ejecting devices to immediately resume their normal position after each ejection, I provide the rod F with the beveled lug it. As soon as the lever moves upward far enough to eject the bundle, this lug 25 contacts with the bevel 25, formed on the loop G, and throws the rod F to one side off of the end of the lever K., When the lower end of the rod F slips off of the le ver K, the weighted angle-lever D causes the ejecting devices to resume their normal position, as shown in Fig. 1, that portion of the said rod F below the beveled lug t resting against the side of the lever K, as shown in Fig. 12. When the forward end of the lever K is again depressed, the rod F automatically swings directly over the same, ready for another operation, the said rod F being sufficiently loosely pivoted to the lever D to permit this swinging movement of the rod, and the rod being bent, as shown in Fig. 5, to cause it to swing. By means of the adjustable clip S on the lever K and the adjustable clips Y Y on the crosshead W the movement of the compressing devices may be adjusted and the size of the bundle regulated at will.

I do not wish to confine myself to the exact construction and arrangement of parts herein shown and described,- as it is evident that persons skilled in the art could vary the same without departing from the scope of my invention.

The advantage in employing a spiral cam to operate the compressing devices is, that the greatest power is obtained where it is most needed. The nearer to the inner end of the spiral cam the pin J gets it'is evidentthat the greater will be the force exerted to elevate thelever K. This maximum of force will be exerted upon the bundle just when the most power is required-that is, when the sticks composing the bundle are being compressed close together.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with bundle-compressing devices and a pivoted lever, K, connected to the compressing devices by means of a connecting-rod, of the drive-shaft and a rotating disk upon the shaft, this disk being provided with a spiral cam upon its face adapted to e11- gage with the said pivoted lever and gradually elevate the same, substantially as described.
